Among the donors is Paul Singer, the billionaire founder of New York hedge fund Elliott Management, according to a receipt filed with the Federal Election Commission. Singer donated $2,700 to Republican candidate Handel via the committee Handel for Congress.

Early tallies from the Center for Responsive Politics show that Ossoff (D) raised about $36,000 from people tied to securities and investment firms while Handel (R) raised about $16,500.

These numbers may change as CRP processes data from fresh donor filings in the coming week, and it's possible that some Wall Street donors haven't yet shown up in CRP's analysis, the group told Business Insider. Still, the data sheds light on who has put money into the race.

There are a number of donors affiliated with big Wall Street firms, including individuals tied Wells Fargo and KPMG, who all donated to the Republican candidate.

Below is a sampling from a more detailed list, per the Center for Responsive Politics. CRP notes that "the organizations themselves did not donate, rather the money came from the organizations' PACs, their individual members or employees or owners, and those individuals' immediate families."

Ossoff's biggest donation - a tally of about $32,000 so far - came from people related to Emory University. Handel's biggest donors came from people affiliated with Cooper Firm, Hennessy Automotive, Northwest Excavating and Rollins Inc. They all tied with donations of $10,800 each.
